It seems that on 08/14/2017 both our Cisco ONS’s now have an alert which wasn’t there previously. These devices are in different cities and one would think something in librenms changed to affect this. These devices haven’t had any issues until this time.
Under limit alert on both devices are exactly the same? #1: sensor_id => ‘4736’, sensor_oid => ‘.22.214.171.124.4.1.3607.2.80.10.1.30.1’, sensor_descr => ‘CHASSIS_454 - POWER BUS A’ #2: sensor_id => ‘4737’, sensor_oid => ‘.126.96.36.199.4.1.3607.2.80.10.1.30.2’, sensor_descr => ‘15454-SA-HD - POWER BUS B’
I’ve already explained this above. The device, via SNMP doesn’t give us a low value to use, well not one apparent in the MIB. Because of that we auto calculate the low value, this calculation can’t be changed and is generic. You can set the low thresholds though yourself by editing the device.
laf I understand what you’re saying but when I look at other Cisco devices in nms and go to edit health their highs and lows have the decimal point and they’re fine, my point is that the high and low voltage for the ONS should be the same as them and have the decimal point
